Small Residential Freezer
How would you calculate how many amp hrs would be needed to run a small residential freezer for say 12 hours with an inverter when you (with out buying it and testing it) when you have no idea how man...

Depends on the freezer.. I have an Engel here it is a Danfoss compressor type, holds, I think 42 or 47 12 oz cans so I'm not sure what that is in cubic feet (will have to measure it next time I defrost). draws 3 amps running, figure 50 percent so in 24 hours that would be 36 amp hours. MOST standard compressor units draw a whole lot more power.
NOTE: both norcold and Dometic make RV fridges (And norcold at least smaller "Cooler" (Chest refrigerators) like my Engle, average door closed power consumption is around 40 watts, Just a couple more than mine, that is still in the 3 amp range at float voltage.. Opening the door on some models may well more than double that when the light comes on!!!!!
